The supremely seductive Komugi has taken on the form of Aoki Hagane no Arpeggio’s blue-haired Iona, showing off the girl’s more promiscuous side by exposing her luscious frame and perhaps drawing more attention to the franchise than the anime’s immensely successful movie.

The cut out spats are from Iiniku Ushijima's Predator Rat line of clothing.
Ushijima san has been really successful with her clothing design.
